This invention relates to new and useful improvements in suspension clamps and the primary object of the present invention is to provide a device for suspending articles from a supporting structure in such a manner, that a large area of the suspended article is available to receive paint or the like.

Another important object of the present invention is to provide a suspending clamp including a pair of gripping members and novel and improved means for simultaneously actuating the members relative to each other.

A further object of the present invention is to provide a suspension clamp including means whereby the same may be adjustably suspended from a supporting structure to accommodate various sizes of articles supported thereby.

A still further aim of the present invention is to provide a suspension clamp that is simple and practical in construction, strong and reliable in use, relatively inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings foming part hereof, wherein like numerals refer to like parts throughout, and in which- Figure l is a front elevational view of the present invention, and with parts broken away and shown in section;

Figure 2 is a side elevational View of Figure 1;

Figure 3 is a front elevational view of the present invention in use, with parts broken away and shown in section; and,

Figure 4 is a longitudinal horizontal sectional View taken substantially on the plane of section line 4-4 of Figure 3.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral Ill represents a suspension rod that is removably secured by any suitable means to a supporting surface in such a manner that the rod is disposed vertically.

Receivably engaged on the lower externally threaded end of the rod IEI, is the hexagonal head portion l2 of a clevis or a bifurcated member I l. The lower end of clevis M supports a removable fastener IE on which is pivotally mounted one terminal portion of an elongated member or main link i 8 having a slot 20 adjacent its lower free end.

Pivotally mounted on opposite sides of member I8 are the inner ends of a pair of upper links 22 and 24 having their outer terminal portions pivotally secured to the opposite sides of a pair of clamping arms or members 26 and 28. The opposite lower ends of the clamping arms are rigidly secured to opposing gripping jaws 30 of preferably angle iron construction which are disposed at right angle to the axis of arms 26 and 28.

The numerals 32 and 34 represent a pair of lower links having their outer ends pivoted on opposite sides of arms 26 and 28. The links 32 and 34, are also pivotally mounted on opposite sides of member l8 adjacent their inner ends.

Slidably mounted in slot 20 is a guide pin 36 having its outer ends pivotally secured to ends of links 38 and 40 pivotally carried by the lower links 32 and 34.

In practical use of the device, by pulling outwardly with one of the arms for example 26, pin 36 wil guide upwardly in slot 20 causing arm 28 to also pivot outwardly, so that an article 42 may be extended between the gripping jaws 30. When the arm 26 is released, the weight of the upper links 22 and 24, the lower links 32 and 34, arms 26 and 28 and jaws 30 will pivot arms 26 and 28 inwardly so that jaws 30 will clampingly engage the article, as shown best in Figure 3 of the drawings.

As previously described, the jaws 30 are preferably of angle iron construction, so that only a small area of the jaws will bear against the article 52, whereby a relatively large area of the article is exposed for convenient painting, drying or the like.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in this art. A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully comprehended by the spirit of the invention as herein described and the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. A suspension clamp comprising a rod removably secured to a supporting structure, a clevis adjustably carried by said rod, an elongated member pivoted at one end to said clevis and depending therefrom, a pair of upper links having inner mans connecting the pin to the inner ends of said,

lower links.

2. A suspension clamp comprising a rod remove,

ably secured to a supporting structure, a clevis adjustably carried by said rod, an elongated flatbar pivoted at one end to said clevis and-having a slot provided adjacent its free end, a pair of upper links having inner ends pivoted to opposite faces of said bar adjacent'said clevis, said upper links having inner faces opposing said bar, a pair'of clamping arms having upper ends pivoted to the outer ends of said upper links and against the inner faces thereof, a pair of lower links pivoted adjacent their inner ends to opposite faces-ofsaid bar, said lower links including inner faces opposing said bar, the outer ends of said lower links being pivoted to said arms medially the length thereof, said arms engaging the inner faces of said lower links, gripping jaws carried by the lower ends of said arms, a pin slidably received in said slot, and further links pivoted to the inner ends of said lower links and against the inner faces thereof, said further links being pivoted to said pin and against opposite sides of said bar.
